If you want to catch the final regular-season games of Derek Jeter’s career, it will cost you.

Ticket prices for the Yankees’ regular-season home finale on Sept. 25 against the Orioles have soared since Wednesday’s announcement the Yankees shortstop will be retiring at the end of the season.

“[That’s] not a surprise,” Chris Matcovich, the vice president of data and communications for TiqIQ, told The Post. “But it is a surprise that he’s retiring, and that it came out of nowhere.”

Before Jeter announced his retirement, the “get-in” price for the game was $26. However, as of late Wednesday afternoon, that price had jumped to $280 — an increase of 977 percent.

The average ticket price for that game also skyrocketed, as it jumped from $304.87 to $803.54, an increase of 164 percent.

When asked how he foresaw the behavior of ticket prices for the game, Matcovich said whether or not the Yankees are in playoff contention will play a large role in determining the prices.

“What will happen is that later in the season, if the Yankees are having a great season, the ticket price will drop,” he said, explaining that if the Yankees look as if they’re going to make the playoffs, the Sept. 25 game will not be the last chance to see Jeter at Yankee Stadium.

Matcovich added people who were able to buy tickets to the game with the hopes of reselling at a later date for more money are taking a risk the Sept. 25 game will be the final game Jeter plays in The Bronx.

That game, which was available on a partial, 12-game ticket plan, was listed as sold out on Wednesday afternoon.

“That plan got sold out,” a ticketing source told The Post. “I’m thinking [the Yankees] took it down because they realize they have the [Sept. 25] game on the plan.”

Yankees ticket officials could not be reached for comment.

Following that game against the Orioles, the Yankees will then head to Boston to close the regular season at Fenway Park, and ticket prices for that game have also ballooned in the immediate aftermath of Jeter’s announcement.

The “get-in” price for that game was $200 as of late Wednesday afternoon, a rise of 96 percent from the price of $102 before the announcement. The average ticket price for that game rose 59 percent, from $249.65 to $397.81.

“The market for this game is one of the craziest we have seen in terms of initial demand and how quickly tickets were taken down from re-sale sites by brokers,” Matcovich said.
